Plate rolling machine is a form of plate rolling equipment, suitable for bending and forming metal plates. It can roll round, arc and conical workpieces within a certain range, and has the function of pre-bending the end of the plate, with small remaining straight edges, high working efficiency, and rough correction of metal plates on the plate rolling machine.
CNC four-roller plate rolling machine is a metal plate bending and correction machine, dedicated to the forming and bending of metal plates. The pre-bending and curling of various specifications of cylindrical and arc-shaped workpieces can be completed after one loading. With the help of auxiliary devices, the conical cylinder can be rolled. It can also perform rough shaping work on metal plates.
The four-roller plate rolling machine can directly pre-bend the end of the plate without the help of other equipment molds. It can roll the workpiece without turning the plate. This not only improves efficiency and ensures the quality of the workpiece, but also has a simple process, easy operation, and reduces the labor intensity of workers.
The working principle of the four-roller plate rolling machine is to use the principle of three-point circle determination to roll different radii. The upper roller is fixed in position and the lower roller moves linearly upward to clamp the steel plate. The rollers on both sides move closer to the upper roller in a straight line or arc to adjust the curvature radius of the roll.
Reasons for heating of the four-roller plate rolling machine
- The pressure adjustment is too high, which makes the plate rolling machine rotate very fast, causing the sealing ring and side plate to burn out;
- The oil tank of the plate rolling machine itself is too small, making the heat dissipation condition poor;
- Internal leakage caused by excessive axial clearance or damage to the sealing ring.
Measures to prevent heating of the plate rolling machine
- When the plate rolling machine is running idle, the noise pressure level shall not exceed 90dB. When the gear transmission, electrical and hydraulic components are working, there shall be no irregular impact sound and periodic screaming. Try to make the mechanical transmission system run normally, smoothly, without abnormal sound, and the brake is sensitive and reliable. Then check that there is no leakage in the hydraulic components and pipelines.
- During the operation of the hydraulic system of the plate rolling machine, the oil temperature in the oil tank shall generally not exceed 50 degrees. After continuous full-load operation for 4 hours, the oil temperature in the oil tank shall not exceed 60 degrees. Hydraulic transmission components should not vibrate, stagnate or impact within the working range. The amplitude of its idle operation should generally not exceed 30μm.
Conclusion
In short, the four-roller plate rolling machine is an important equipment in the production of enterprises. During the operation of the plate rolling machine, it is necessary to continue to follow the equipment process requirements, operate correctly, and actively maintain and repair it to extend the service life of the equipment!
